I have updated the text of one of my snippets. I wait for it to save then try it out. The old text keeps coming up, not the new text. I have deleted the snippet, recreated it, refreshed the screen and logged out. The new text will not save.
Hi, and welcome to the forum! 
Can you try reloading your extension and see if that fixes it? Just right-click on any webpage and select "Reload extension" under the Text Blaze menu.
Let us know if that fixes it for you.
